The metal clips shown use non-locking gates — examples include wire-gate and straight-gate designs. No locking (screw or auto-lock) mechanisms are listed.

They work on many smooth, finished surfaces such as painted walls, finished wood, glass, tile, and metal; other listed surfaces include stone, laminates, mirrors, vinyl siding, brick, and stainless steel.

Described as weather resistant and rated for temperature extremes from -20°F to 125°F.

Sizes range from small carabiner clips at about 1.6 inches long to rope-tightening units around 8.1 inches, with several wall hooks listing overall heights or lengths in the 4–6.75 inch range.

They are described for attaching ropes, backpacks, and similar lightweight camping and hiking gear, but are explicitly labeled "Not suitable for climbing adventures."
